LOCOMOTIVE WITH HAULAGE MECHANISM` Sipecilleation of Lette-rs Patent.

Patented 31113' 1S, 19 1 T0 all @cfm/u. it may concern:

Be it known that l, FRANK L'. Sessions, citizen of the United States, residing at Columbus, in the county ofFranklin and State of Ohio, have invented certain new and useful' Improvements 'in Locomotives with Haulage Mechanism, of which the following is a specification, reference being had therein to the accompanying drawing.

A locomotive embodying the invention is adapted primarily for use in and about coal or other similar mines for hauling theseparate mine cars from the rooms, or I other places in which they are loaded, and collect ing them into trips or trains to be thereafter hauled from the mine. Under many co'ndi tions it is impossible for the locomotive itselfeven when provided with an electric cable reel mechanism or other means for supplying electric current, to enter into thc rooms to be attached directly to the cars. Under Isuch circumstances use is made of a locomotive having u haulage cablewhich canbeunwound from a reel on the locomotive and its end taken into a room and connected with the car. And then, by suitable power mechanism, the reel is turned n'd the cable is wound u on it, the car being hauled out to a point c Osely adjacent the locomotive.

One object of this invention is to vprovide in :1 locomotive of this general class an improved driving mechanism for the locomotive and for the rcel.

Another object is to provide an improved mounting for the reel and an improved general arrangementof the reel with respect to the other locomotive parts.

i For the Asake of economy in Iirst'cost, and in order to reduce the weight, it is, under many circumstances, found desirable to use `a single motor, or a sin le set of motors', 'and to provid: gearing w ereby them'otoi -or motors can li used either to drive the locomotive itself or to' drive the reel, or to drive both simultaneously. lBy n'iy invention, I have introduced a differential vgearin -hetween the motor on'the one hand'ifzn the locomotive track wheels and the reel lon the other hand, and have provided suitable brake mechanism whereby either the locomotive wheelsxmay be locked and the power transmitted to the reel, or whereby the reel may be locked and the powerftrnnsmitt'd to the Wheels Oli', if desired, the wheels and the reel may' both be left'free and power transmitted to rotate both of them` simultaneously. By my invention 'I have also provided e novel and advantageous mounting for the reel. l mount the rcel concentricallv with one of the main axles, preferably supiporting it directlyupon the axle.. ln this way a very compact arrangement of the operative parts is provided, the driving gearing is greatly simplified, and the reel is firmly held in its true position.

In the drawings-Figure 1 is a plan view of the -locomotive as a whole. Fig. .2 is a side elevation of the same with parts of the locomotive broken away to show the interior construction. Fig. 3 is '.1 vertical cross section of the rear axle and :issociatcd parts. Fig. 4 is a fragmentary elevational view "showing the differential gearing.

p The frame of the locomotive, comprising the side castings 1,` l, :md the end castings 9., 3, is supported upon the front and rear axles al and 5 respectively, upon which are secured the track wheels (3. At the rear end of the locomotive are arranged the motormuns sent T and the controlling mechanism, such as thc controller 8, brake wheel 30, etc.

The motors 10, 10, are supported in any suitable manner and are geared by means of the pinions 11, 11 to thc gear wheels 12, 12, respectively. Each of those gear wheels 12, 12 is loosely mounted upon one of the locomotive axles 4 and 5 and has jimrnaled with in it upon radial axes the bevel pinions 13, 13. The pinions of each geur wheel 12 mesh on one side of the wheel with a bevel gear wheel 14, which is keyed to its axle and is ada lted to drive the track wheels and to proliel lthe locomotive bodily. The bevel pinions 13, 13 of each "enr wheel 12 also mesh on the other side oft-he wheel with the bevel gear wheel 15, which is mounted to turn freely withrespect to the axle upon which it is sleeved.

rhe gearing which has just been described constitutes a di fferential power transmitting mechanismI for connecting the motor with the wheels and with the drum in such a way` that eachV receives equal torque irrespective of the speed at which it may be permitted to move.l A w g l The gear-.Wheel 15 isl adapted t0 d ive the diuriirl and, for that purposeis hrought into frictional engagement with the drum in the following manner. The drum is lloosely mounted upon thc axle so that it can freely t turn with respect thereto and can-be moved in .Lu

longitudinally. The friction ring 17 on the gear wheel 15 is adapted to coact with the conical face 18 upon the drum. To bring the friction ring into contact with the drum the clutch shifter, indicated as a whole by 19, is employed. The stationary ring .20 of this clutch shifter is formed with a spiral end face 2l, which fits against a correspondngly shaped m'ovable ring 22. This ring 22 can berotat'e'd by means of th rd 23 to force the drum against the friction ring 17. By means of the spring 23 this rod is feld yieldingly in such a o'sition as to maintain the drum in fricti'ona Contact with the gear wheel 15.

'lhe rod 23 extends through an aperture in the. vertical bracket 23" and is provided near its end with downward opening notches zo adapted to 'engage the bracket. At the end of the rod 28 1s a handle 24- and by means of this any one of the several notches can be engagedA with th'e bracket so as to vary the pressure between the drum 16 and the friction ring 17 or to hold the drum entirely out of engagement with the friction rin Lach gear wheel 15'is provided with an annular recess 25 about which is fitted a brake band 20; The two brake bands 2G are o erated in unison by means of the threa'c ed rod 27 and ahand wheel 28 the latter being within reach of the operator as he sits at the rear end ofthe locomotive. The brake mechanism, indicated as a whole biy the numeral 29, is provided as usual for clocking or stop )ing the rotation of the track wheels; an is under the control of the operator by means of the. hand wheel 30. Upon the gear whe'els l are cut the teeth of the sprocket wheels 31; 31', about which is place( the sprocket chain 32. 'lhus the two motors coperate to rotate the drum in the saine mu'nncr that they rotate the track wheels wh'en the propo'r power` transmitting connections are ma'de.

Upon the Idrurh 16 is wound the haulage or drive cable 33 which is conducted from the drum between the guide shcaves 34 mounted in the draw-liar ockct or slot 85 formed inthe front end frame 2 of the locomotive. .The cable isprovided a't its free end with a coupling hook 36 by which it can be secured to the. c'ar or train of 'ciirs which are to be hauled.`

The manner 4inw'hich this locomotive is o. erated will be quite readily apparent from tie description of the working parts. When the ocomotive i@ coupled to a train of cars by r'neans of its draw-bar, and the cable 33,is notjnoperation', the gear \vlels 15 Iare held stationary bymeans ofl the brake bands and tbe hand wheel 28 and the rotary motion-of the motors is transmitted wholly to the truck wheels. "'hen it is dcsired to hoist loaded cars up steep inclined track-anys from what are known as dip` rooms, and into which it is not practical to run the locomotives, the locomotive is held stationary at the top ol the grade by setting the brake mechanism 25), the motor is started and the drum lo is rotated to wind up the cable and haul the cars out oi' thi` various rooms in which they have been loaded. Daring such operation the brake bands 2li are released and th'e spring operated clutch shifter 19 is released so that the drum is held in frictional contact with the gear 15.

When it is so desired the cable can be used as a coupler in hauling the cars along the entry-way from room to room while they are heilig gathered. lt is also possible with this locomotive, if it should be found advantagcous, to lower the cars into the rooms by holding the gear wheels 15 stationary and controlling the unwinding of the cable 33 by means of the clutch shifter 1l), which can be used to increase or decrease the friction between the drum and the stationary gear wheel 15.

lVhen the locomotive is pulling a. ear or train of cars and an exctaitionally steep grade is about to he. traveled, the. cable drum can be released so that the car or cars will remain at the bottom of thel grade while the locomotive ascends it and after the locomotive has reached the to) the brakes can be set and the hoisting mcciianisin employed to pull thc cars up the grade after the locomotive.
